COAL-STOVE.

SPECIFICATION forming part of Letters Patent No. 331,623, dated December 1, 1885.

Application filed May 11, 1885. Serial No. 165,061. (No model.)

of Connecticut, have invented a new and useful Improvement in Coal-Stoves, of which the following is so full, clear, and exact adescription as will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a perspective of my improved stove, with a portion of the casing broken away, thus showing the structure of the interior. Fig. 2 is a plan view of the bottom of the stove, showing the revolving grate, the perforated damper, 8:0. Fig. 3 is a crosssection of Fig. 2 on the line a :12, which shows the groove in the outer periphery of the revolving grate, the pinion which operates the perforated draft-plate, and also the pinion which operates the revolving grate. Fig. 4 is a detail to be referred to.

My invention relates to heating-stoves; and it consists in the novel construction, combination, and arrangement of parts, as will hereinafter be fully set forth, and specifically pointed out in the claims.

In the drawings, A represents the casing of the stove, the upper part of which forms a radiator and heating'drum.

B is a basket-grate or fire-pot, which is secured to the perforated damper-plate O at a suitable distance from the walls of the casing A. By reference to Fig. 1 it will be observed the fire-pot is much smaller than the casing A, which leaves considerable space between the outer surface of the fire-pot and the inner surface of the casing A.

D is a revolving grate,pivoted at its center to the bar a by the pin 1), which extends through a hole in the bar a, and is secured in position by a key, 0. The bar a. is provided with a pair of twin projections, which extend at right angles to the bar, and which form supports for the revolving grate D. This grate D is provided at d with a groove, which extends completely around the periphery of the grate and serves as a guide, in which the arbor e extends,which allows the grate to rotate, and at the same time prevents the grate from dumpmg.

F is a pinion, which serves as a means of revolving the grate D.

On the top of the perforated damper-plate C is a slide, E, which is also provided with elongated holes g g, which register with similar holes, h h, in the damper C.

Ati is a rack-bar in the slide E, which registers with the cogs j on the arbor c. This arbor c is also provided with a pin, K, which extends through it at right angles, and forms a sort of bayonet-fastening in the T-shaped slot tin the damper-plate C, as shown in Fig. 4. The object of this T-shaped slot land pin K is to allow the arbor e to be withdrawn from the groove d, to allow the dumping of the grate when it is desired to do so. This arbor 6 also serves as a means of operating the slide E, by simply turning it with the thumb and finger, the cogs j meshing in the rack-bar i.

The operation is as follows: Fill the fire-pot in the usual manner, and when it is desired not to have a very hot fire, open the draft by operating the slide E with the arbor e. When it is desired to increase the amount of heat in the room, close or partially close the draft by simply turning the arbor e in the opposite direction. When it is desired to dump the grate, give the arbor e half a revolution, withdraw it till it clears the grate, and then dump the latter by turning the bar a.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a casing, a perforated damper-plate, a correspondinglyperforated slide, an open basket-grate or fire-pot supported upon the damper-plate, a revolving grate having a peripheral groove, an arbor with toothed wheel for operating the slide, said arbor passing through the damperplate and guiding the movement of the grate, and a pinion for revolving the grate, substantially as herein described.

2. In a stove, the fire-pot, the casing, and the revolving grate having a grooved periphcry, in combination with the perforated damper, the corresponding]y-perforated slide, and

the arbor e, which serves the double purpose of a guide for the grate and a means of regulating the draft, substantially as set forth.

3. In a stove, the combination of the easing, the fire-pot supported therein, a chamber between the fire-pot and easing, the revolving grate having a groove in its periphery, a sliding arbor engaging the groove, and a toothed wheel engaging teeth on the bottom of the grate for revolving the latter in either direct-ion, sub- 10 stantially as herein described.
